Can I create an array of objects in a circular pattern in BricsCAD?

ByCADbrief Staff

Short Answer

Yes — in BricsCAD, you can create an array of objects in a circular pattern using the ARRAYPOLAR command, which is the standard professional method for radial repetition around a center point. It lets you control item count, angle fill, and associative behavior quickly. Limitation: very complex source objects can make associative arrays harder to edit.

What You Need to Know Before

Warning: If the base objects are on locked layers or include unsupported nested content, the polar array may fail to create or may not remain editable as expected. A very common mistake is picking the wrong center point, which shifts every copied item into the wrong rotational path.

How-to

  • Command: ARRAYPOLAR

  • Shortcut: AR

  • Quick Steps:

    1. Start ARRAYPOLAR from the Ribbon > Home tab > Modify panel > Array, then choose the object(s) to repeat and press Enter.
    2. Specify the center point of the circular pattern carefully using object snaps if possible.
    3. Enter the number of items and set the fill angle; keep the Associative option turned on if you want to edit the array later.

Variables & Settings

  • Key Setting: Associative array option

  • Expert Setting: When Associative is enabled, the polar array stays linked as one editable array object, making later changes to item count, angle, and spacing much faster. If turned off, the result becomes separate copies and loses array-editing flexibility.

Why it Fails

  • Cause 1 (Geometry): The selected center point is incorrect, so the objects rotate around the wrong location and the pattern appears misplaced.
  • Cause 2 (Layers/Locks): Source objects are on a locked layer, or the current layer setup prevents proper modification or display of the new array items.
  • Cause 3 (Command/Logic): The array is created as non-associative, so users expect editable grips and array options but only get static copied objects.

Quick Fix & Best Practice

  • Quick Fix: Run ARRAYPOLAR again, use object snap to select the exact center point, and make sure Associative is enabled before finishing.
  • Manager’s Verdict: Use polar arrays for evenly spaced radial layouts like holes, fixtures, and symbols; avoid them when each instance needs heavy individual customization after placement.

FAQ

Can I edit the number of items after creating a polar array?

Yes, if the array was created as associative, you can change the item count afterward.

Can I make a full 360-degree circular array in BricsCAD?

Yes, set the fill angle to 360 degrees.

Can I array blocks in a circular pattern?

Yes, blocks are commonly used with ARRAYPOLAR for clean and efficient circular layouts.
